"Animals are often used as a tool for emotional abuse," says Marshfield Police Chief Phil Tavares. "The batterer, the abuser will use an animal to seek revenge on or try to control one of the victims."

According to CBS Boston, more than 70-percent of abused women say their abuser either threatened their pet or actually hurt the animal. Police say that's why many victims don't leave.

The hope is the new law will change that, empowering victims to leave and giving their pets a safe haven.

CBS Boston reports Panzer's owner couldn't stay in Massachusetts because all of the state's domestic violence shelters were full. Once she and her son find permanent housing, they expect to be reunited with their pet.
